where \(1/128\)  comes from \(1/(64\times 2)\)  due to the convention that \(K_{JSJ}\)  corresponds to the coefficient of \(2 J_{L}^{a} S^{a b} J_{R}^{b} \) . In the massless limit of \(g_1(m|X|)\)  and \(g_1(m|Y|)\) , Eq. (REF ) reproduces the corresponding massless limit of Ref. [1]} (Eq. (4.36) therein). As discussed previously, the final result
\(K^m_{JSJ}\)  is obtained after subtraction
\(K_{JSJ}^{m} = K_{JSJ}^{\prime m}-\frac{1}{2}\int _{\mathbf {z^{\prime }}}K^m_{q\bar{q}}(\mathbf {x,y,z,z^{\prime }})\)
